Application filed March 11,1925. Serial No. 154,840.

My invention relates to a roll of a gelatin sheet that is used in making copies on What is known as the hectograph principle.

The object of my invention is to furnish a form of roll that may be conveniently handled and that will .cost less money in making, mounting and handling than has heretofore been used withgelatin rolls.

A further object fmy invention is toprovide a spindle upon'whiehthe gelatin roll is mounted in its use in a machine where rolls of thiskind are used.

Reference will be had to the accompanying-drawing in which Fig. l is an elevation of one of my rolls mounted on a spindle.

Fig. 2 is a longitudinal sectional eleva tion of what is shown in Fig. 1.

Fig.3 is an elevation ofa middle portion of the roll spindle showing the attachment of the roll to the spindle.

Fig. 4 is a section on' line &4: of Fig. 3.

Fig. 5 is a plan .view of the end of the roll sheetboth ends being alike.

F ig; 6 is'a section on line 6.6 of Fig. '1. Fig. ,1 is an end view of the spindle being what amounts to an end of either; end .of'Fi'g. l'or Fig. 2. p F g. "8 shows a wooden spindle. I

These gelatin rollsare made-with a paper or cloth backing on which there s provided a elatin composit on face'on one side.

They are made n widths suiting the widths'desired to. be. .used 111 copying. work, of varying widths ranging from nine to twenty inches.

They are made in various length, buttlie usual length is about'15 feet and when thissheet of gelatinized -fabricis rolled up it makes a'roll of approximately four to four and one-half inches in diameter.

It is customary in the use of these rolls. to use them in a'machine and the rolls are mounted on spindles oneateach end of the sheet to which-thesheet "is" permanently, attached, as has heretofore been the general custom.

Thus each time a roll is manufactured and shipped for use there goes along with it two spindles which have become a part, as it were, of the roll itself in service.

With my roll, I provide what may be termed permanent spindles that remain with the machine in which the rolls are used, and the rolls themselves as made by the manufacturer are mounted upon temporary spindles usually madeof paste board and used only for handling and transmission to the user 'of-the-rolls.

'When the rolls reach the customerhe unwinds the rolls from the shipping spindle onto the service-spindles of the machine, and I provide a peculiarly meritorious designfor -tlie-.ends of theroll sheetsthat adapt them to this handling and transfer from the temporary sheet spindle tothe permanent service spindle and thus I save the cost of what has heretofore been the practice of shipping with each new roll the ,two service spindles.

I accomplishthis advantageby providing the ends of the roll strips with end or tuck straps adapted to engage the spindles in the winding operation and adapted to form a closure for the loose end ofthe roll sheet when-the saine'is wound uponit-selt to complete form.

In the drawing, 1 indicates the main body of-the gelatin roll, which is fastened by a seam 2 to a cloth end 3 adapted'to be the armor or protecting coating-around the roll when the-same is wound up.

This ,cloth length issufiicient to'a little more than entirely enwrap the enti're'fl-cir- .cumferenceof the gelatin roll when the same 7 is wound up. i I On the .end of this cloth end of the roll sheet 'I-provide a strap'end' land ata distance back from theend'of the cloth end amounting to the. circumference of the :wound up roll. I provide a keeper' piece 5 sewed onto the cloth 3underneath which the .end of the strap 4 nay be tucked as shown in Fig. 1 in order to .hold the roll from automatically unwinding.

The keeper-piece 5 is slitted atG .so that the end of ,the straps: may be inserted at this slit as is .shown in Fig. 1, or the strap maybe inserted under the edge-of. the keeper pieceeat the. edge thereof as indicated by 7. The purpose oflthis slit 6 inthe keeper piece 5 is'to permit'the' strap to be engaged thereby when the roll is a little larger or a little smaller due to the swelling or the shrinking of .the gelatin under the influence of more or less moisture.

The service spindle is indicated as 8 being a tube provided with end flanges 9 permanently'secured thereto and provided with a diameter slightly larger than the largest diameter of the roll as a body indicated by 10, the single web of this roll being indicated by 1 as before mentioned.

The end flanges 9 are sufficiently large to allow the spindle with a roll mounted. there on to be laid on the table or on the floor or any suitable position without the roll body 10 getting in contact with the floor or being distorted or injured when several rolls are run down a chute guided by end flanges 9 of the spindles.

The end flanges 9 and the ends 11 of the tubular spindles are notched out at 12 for engagement with the driving mechanism of the machine in which the rolls are used.

The central portion 13 of the tubular spindle 8 is made smaller in diameter to permit the winding thereon of the strap ends 4 without causing a bulge in the body of the gelatin portion of the sheet when it is wound upon the spindle.

This portion 18 of the spindle 8 is slotted by slots on opposite sides as is indicated by 14 for the purpose of engaging the strap ends 4 to start the winding of the roll sheet onto the spindles and this is accomof the roll and the roll is used in the copy.

work it is wound from one service spindle onto another commencing with a vacant spindle upon which there will then accumulate the used roll until the entire roll is on that spindle leaving vacant the first spindle which is then ready for receiving a fresh roll upon it as the fresh roll is used in the service of the machine.

These service spindles 8 are made sufliciently substantial. to stand a continual service in the use of a machine of this class and a sufficient number of them is provided to carry all the rolls that any given user may desire to use from day today in this copy work.

The shape and construction of the roll web or sheet as described permits the use of these service spindles and saves the elpense of the regular service spindle-s that heretofore have been shipped and used only with a single roll; when that roll is worn out it has been the practice heretofore to not only discard the used up roll but often also the service spindle which Went with it.

Thus by my invention I bring about a great economy in the use of these gelatin copy rolls.

The service spindles with their flanges 9- which permit the spindles as individuals to be rolled down a chute and a. stock of them carried in a chuteway with the rolls mounted on the spindles, permits the storage and handling of rolls in a more compact and convenient way than has heretofore been accomplished by any meansknown tome.

I Vhen spindles are desired without the end flanges and with the 'old. style end gudgeons heretofore used, I provide the spindle in the form of Fig. 8 which may be made of wood and be made smaller in the center as indicated by 1.5, and be provided with a slot 16 through the body similar to slot 14 and used in the same way.

The novel spindle claimed in this application is also shown in my co -pending applications Ser. Nos. 26,777 54,750; and 108,058; and the right to claim this novelty is expressly reserved.

lVhat I claim is z- 1. In a spindle of the class described, the

combination with a central "tubular body portion, of annular" ends of relatively thin material having outwardly extending concentric internal and peripheral flanges, said internal flanges fitting over and rigidly united to said body portion, with terminally open notches through said internal flanges and body portion.

2. A gelatin roll spindle having a central cylindrical portion joinedto terminal body port-ions by outwardly flaring conical portions, longitudinal slot in sald central portion and terminal winding teeth, and annular ends each having an outwardly extending internal flange fitted over said body, rigidly united thereto and having winding teeth continuous with said first mentioned teeth, and a peripheral outwardly turned supporting flange serving to protect said teeth.
